The verdict
A premium pick for large TVs where the final height matters, such as above a fireplace or a console, because the screen can be moved up or down after it is hung. Before buying, confirm that your TV's mounting pattern falls inside Sanus's listed range and that the wall is wood studs at least 16 inches apart, solid concrete or concrete block. Abt lists a 10-year limited warranty.
The VLF828-B2 is the large model in Sanus's Advanced Full-Motion 4D + Shift line, built for 42 to 90 inch TVs weighing up to 125 lb. Its SHIFT feature raises or lowers the TV up to 4 inches from center after installation, using a twist handle that tucks behind the screen, which helps above a mantel or when a soundbar is added later. It sits 2.42 inches from the wall when folded, reaches 28 inches out, tilts 5 degrees up and 15 degrees down, swivels up to 46 degrees each way and routes cables through the arm.
Strengths
- SHIFT height adjustment moves the TV up to 4 inches up or down after installation, 8 inches in total.
- Rated for 42 to 90 inch TVs up to 125 lb, with mounting patterns up to 600 x 400 mm.
- Reaches 28 inches from the wall yet folds back to 2.42 inches.
- The manual includes a level adjustment after mounting, plus tension controls for tilt and arm movement.
- Cables run through the arm under removable covers for a tidier look.
- Abt lists a 10-year limited warranty.
Weak spots
- Installs only into wood studs at least 16 inches apart, solid concrete or concrete block, never drywall alone.
- Sanus's spec sheet gives the smallest pattern as 100 x 200 mm while Abt also lists 100 x 100, so a small pattern needs checking against the manual.
- On concrete or block walls the arm must stay centered on the wall plate, so the sideways repositioning option applies to wood stud installs only.
Great for
- Large TVs mounted above a fireplace or console
- Rooms where the TV height may need to change later, for example to add a soundbar
- Viewers who want reach and swivel without a bulky folded profile
Skip if
- Drywall-only or metal stud walls
- TVs heavier than 125 lb or larger than 90 inches

Setup notes
- Sanus's spec sheet lists mounting patterns from 100 x 200 mm up to 600 x 400 mm; Abt's listing also names 100 x 100, so confirm a small pattern against the manual before buying.
- The 125 lb limit includes anything attached to the TV, according to the manual.
- Wood studs must be at least 2 x 4 in nominal and at least 16 in (406 mm) apart, with drywall no thicker than 5/8 in; solid concrete must be at least 8 in thick, and concrete block at least 8 x 8 x 16 in.
- For concrete or block installs the arm must remain centered on the wall plate.
- After mounting, turning the SHIFT handle raises or lowers the TV up to 4 in from center.
- Fully extend the arm before routing cables through it so they keep enough slack, per the manual.
